Install node on Apple Silicon M1 both ARM and x86 (Rosetta)

Node.js on Apple Silicon

Node Version Manager (https://github.com/nvm-sh/nvm) works perfectly across native node installations as well as emulated Rosetta installations. The trick I am using here is to install one LTS version of node under Rosetta and another stable version as native binary.

TODO

  • find a way how to run the same node version on both platforms
# Run the install command from a native (ARM) terminal
# See https://github.com/nvm-sh/nvm#installing-and-updating
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
# Alternatively install using brew (officially unsupported by nvm):
# brew install nvm
# Don't forget to source the command in your shell profile to make it available in new terminals!
# From Rosetta Terminal (tick checkbox in Terminal right click menu -> Get Info -> Open using Rosetta)
# To verify you are running in Rosetta run:
arch
-> i386
# Install node
nvm install lts/fermium
# Verify node installation
nvm use lts/fermium
node -e 'console.log(process.arch)'
-> x64
# From native Terminal
# To verify you are running natively:
arch
-> arm64
# Install node
nvm install stable
# Verify node installation
nvm use stable
node -e 'console.log(process.arch)'
-> arm64
# To make DX a bit better you can alias your installations:
nvm alias arm stable
# arm -> stable (-> v15.6.0)
nvm alias intel lts/fermium
# intel -> lts/fermium (-> v14.15.4)
# To test aliases:
nvm use arm
# Now using node v15.6.0 (npm v7.4.0)
node -e 'console.log(process.arch)'
-> arm64
nvm use intel
# Now using node v14.15.4 (npm v6.14.10)
node -e 'console.log(process.arch)'
-> x64
